[Rifleman-7.62]

I have had problems with Magtech brand brass cased 7.62 x 51 on light primer strikes with a certain rifle. But I have not had problems with Magtech on any other firearm.

I bought some 7.62 x 39 Geco ammunition and had continual problems with failure to feed in an AR-15.

In my AR-15 rifle I use Russian steel cased Tula and Wolf 7.62 x 39 ammo and I have no problems with it that I can discover. But I do not like Russian steel cased ammo in pistols.

Blazer .45 Auto and 9 millimeter Luger brass cased ammunition I have no problems with.

Thus far I do not like aluminum cased ammo because of problems with it. I now try to avoid it.

So my naughty list for ammunition is: Magtech 7.62 x 51 brass cased, Geco brand ammo and aluminum cased ammo and steel cased pistol ammunition.

A 420 round can of Federal XM855 I bought a long time ago was pretty horrid. Ten inch groups from a 16 inch 1:8 twist barrel at 60 yards. I thought there was something wrong with the rifle until I tried some Hornady ballistic-tipped rounds and it shot near Minute of Angle. First Federal ammunition I've ever had an issue with.

Even cheap Russian rifle ammo out performs that. I do not expect better than 2.5 inch groups at 100 yards from Russian steel cased ammo. Some ammunition batches just were done with shoddy quality. I get better groups than that firing 9 millimeter Luger pistol ammunition from an AR-15 carbine.
